Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following best explains the purpose of cell respiration?
A
In cell respiration, sunlight is used to make sugar
B
In cell respiration, sunlight is used to make ATP
C
In cell respiration, glucose is used to make energy
D
In cell respiration, oxygen is used to make sugar
Explanation: 

Detailed explanation-1: -Cellular respiration uses glucose and oxygen to make carbon dioxide, water, and ATP. The molecule ATP is used for energy to run cellular processes. Carbon dioxide is released to the atmosphere where it is used in photosynthesis by plants. The process of photosynthesis uses ATP for energy to build glucose.

Detailed explanation-2: -Answer and Explanation: Cellular respiration is best described as E) changing of stored chemical energy in food molecules to a form usable by organisms.

Detailed explanation-3: -Glucose’s role in cellular respiration is essential, as it provides the building blocks for ultimately creating ATP, the energy currency used by living organisms. The structure of glucose with carbons numbered. Cellular respiration refers to the breakdown of organic molecules into energy.

Detailed explanation-4: -During cellular respiration, NADH and ATP are used to make glucose. ATP synthase acts as both an enzyme and a channel protein. The carbons from glucose end up in ATP molecules at the end of cellular respiration. Energy is stored within the chemical bonds within the glucose molecule.

Detailed explanation-5: -Glucose is the most important substrate of cell metabolism. It is the carbohydrate fulfilling the task of being the energy transport system of the body. Several parts of the body like the nervous system or blood cells are completely dependent on glucose as the supplier of energy.
